Title: Voltage controlled oscillator
Inventor: UZAKI TETSUYA
IPC: H03B5/18
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To provide a voltage controlled oscillator from which an oscillation signal with excellent linearity of a control voltage versus oscillating frequency is obtained over a broad band. SOLUTION: An inductive circuit section 1 of a Colpitts type voltage controlled oscillator is provided with a parallel circuit consisting of a resonator 12 being an inductive element and a varicap diode X1. The inductive circuit section 1 is also provided with stub circuits 11-14 to add an additional capacitance Ca to the parallel circuit. Through the proper application of a control voltage Vv from the control terminal P1 to P4 , the capacitive stubs S1-S4 of the stub circuits 11-14 are connected sequentially in cascade to the parallel circuit and the additional capacitance Ca is sequentially increased. Since the additional capacitance Ca of the voltage controlled oscillator is changed into four stages, a change in the oscillating frequency F is extended to be nearly four times under the condition of applying control voltage Vv of the same voltage range to the diode X1.

IPC: H05B3/44
Filed: 1994-08-08
Abstract: PURPOSE:To provide a heat generating body at a low cost which efficiently absorbs bad odorous gas, has excellent oxidation decomposing property, and maintains a stable high deodorization effect for a long time. CONSTITUTION:This heat generating body consists of a casing 3 such as a glass tube housing a heating member 1 which generates heat when an electric current is applied, and an oxidative decomposing and deodorizing catalyst layer 4 deposited on the outer surface of the casing 3. This oxidation decomposing and deodorizing catalyst contains active manganese dioxide, zeolite which carries copper ion, and copper oxide as effective components preferably with weight ratio of 1:(0.5 to 1):(0.05 to 0.5). This oxidation decomposing and deodorizing catalyst adsorbs sulfur-base bad odorous gas such as methyl mercaptan. By generating heat from the heating member 1, the oxidation decomposing and deodorizing catalyst layer 4 is heated through the casing 3. The odorous gas adsorbed on the catalyst is easily decomposed with this heat by the active manganese dioxide having high oxidation activity, and thereby, the deodorizing function of the catalyst layer 4 can be easily recovered and regenerated.

Title: Poisoning-preventive catalyst and carrier with poisoning-preventive layer, exhaust gas purification device and poisoning-preventive gasoline composition
Inventor: KOJIMA TAKAO
IPC: C10L1/30
Filed: 1990-08-06
Abstract: PURPOSE:To prevent a noble metal catalyst from being poisoned with Si to avoid the lowering of the catalyst performance by incorporating the compounds contg. the group IIa elements in the periodic table in the side exposed to the exhaust gas of the poisoning-preventive layer. CONSTITUTION:In a vehicular device for purifying exhaust and digestion gas using a catalyst of noble metals such as Pt and Rh, a compound 13 contg. the group IIa elements in the periodic table such as Mg, Ca and Sr is incorporated in the side thereof more liable to exposure to the exhaust gas than the catalytic components 12 of the noble metals, particularly the outermost poisoning-preventive layer. In this way, the poisoning components such as Si and P contained in the exhaust gas are captured by the compound of the group IIa elements before reaching the catalytic noble metal components. Therefore, the possibility of such catalytic components being poisoned or clogged with silicon or phosphorus is reduced and the lowering of the purification performance is thus made difficult.

Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To reduce the temperature during operation of bearings which pivotally support a rotating portion, slow grease deterioration and increase bearing life, and eliminate the need for balancing, which is troublesome, when replacing the bearings. SOLUTION: An internal motor type axial fan is realized by: a rotating portion wherein a motor rotor 6A is disposed fixed to a shaft 1, and wherein moving blades 9A, 10A are disposed on both sides of this rotor 6A; bearing housings 11, 12 which rotatably pivotally support the outside of this rotating portion in the axial direction via a bearing 3 while being fixed to a case 4 via stationary blades 11A, 12A disposed on the outer periphery; and a stator 5 which internally holds a motor stator 6B disposed opposing the outer periphery of a motor stator 6A while having a stationary blade 5A disposed on the outer periphery thereof, and which is fixed to the case 4. Accordingly, having the bearing 3 positioned at the end of the axis of the rotating portion decreases the bearing temperature, slowing the deterioration of the grease and enabling the life of the bearings to be increased.  Furthermore, the bearings are disposed on the outside of a nut 2 that screws onto the moving blade body 9, 10, thus eliminating the need for disassembly when changing the lubricating oil of the bearings or changing the bearings themselves, which disrupts the rotation balance, and therefore eliminates the need for balancing.
